Description

Technical Field

[0001] The utility model relates to the technical field of medicine stirring, in particular to a novel medicine stirrer. Background Art

[0002] The operating temperature of bearings on most existing pharmaceutical agitators generally does not exceed 80°. However, in the actual production process, the bearing temperature often rises due to insufficient bearing lubrication, excessive viscosity of lubricating oil, and bearing processing and installation. Excessive bearing temperature will cause material expansion, resulting in a decrease in mechanical clearance, noise and mechanical damage.

[0003] After searching, a Chinese patent with authorization announcement number CN221107787U discloses a technical solution to the problem of increased bearing temperature. The low-boiling-point liquid and the heat dissipation copper tube extending upward in a spiral cooperate to dissipate heat from the bearing, and is equipped with a manual pressure reduction unit for adjusting the air pressure in the annular cavity and the heat dissipation copper tube. However, the above heat dissipation method has some problems. When the heat dissipation speed of the heat dissipation copper tube is lower than the low-boiling-point vaporization speed, the air pressure in the inner cavity of the heat dissipation copper tube will increase. As the air pressure increases, the boiling point of the low-boiling-point liquid will increase, resulting in an increase in the vaporization temperature of the low-boiling-point liquid, which in turn makes it increasingly difficult for subsequent low-boiling-point liquids to vaporize. The low-boiling-point liquid cannot conduct the temperature on the bearing away in time, which will cause the bearing temperature to increase, affecting the heat dissipation of the bearing. Therefore, this application provides a new type of pharmaceutical agitator to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a novel pharmaceutical agitator for solving the technical problem in the prior art that the heat of the bearing cannot be transferred to the shaft in time as the air pressure in the heat dissipation copper tube becomes higher and higher.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a new type of pharmaceutical agitator, comprising a stirring motor installed on a frame, the output shaft of the stirring motor being connected to the stirring shaft through a mounting shaft, the mounting shaft passing through the frame, the outer sleeve of the mounting shaft being provided with a bearing, and the bearing being installed together with the frame through an upper bearing seat, the inner cavity of the upper bearing seat being provided with a liquid storage cavity, the liquid storage cavity storing a low-boiling-point liquid, a heat dissipation copper tube communicating with the inner cavity of the liquid storage cavity and extending spirally upward being installed on the upper bearing seat, and also comprising an air pressure self-balancing adjustment unit for ensuring the air pressure balance in the heat dissipation copper tube, so as to achieve good heat dissipation of the bearing by the low-boiling-point liquid.

[0006] As a preferred implementation manner in this embodiment, the air pressure self-balancing adjustment unit includes a hollow cylinder fixedly arranged on the outer wall of the frame through a mounting plate and a column sliding through the limit plate, the limit plate is fixedly mounted on the frame, the lower end of the column is slidably arranged in the inner cavity of the hollow cylinder, the lower end of the column is fixedly sleeved with an elastic sealing ring that slides in contact with the hollow cylinder, the upper end of the column is provided with a material receiving trough, and the bottom surface of the inner cavity of the material receiving trough is set as an inclined surface, the inner cavity of the material receiving trough is provided with a small weight block, and the lower end of the material receiving trough is provided with a discharge pipe with an electric valve;

[0007] A hollow tube with a sealed upper end is installed on the mounting plate, and a spiral push rod driven by a driving motor is rotatably provided in the inner cavity of the hollow tube. A discharge pipe is provided on the hollow tube obliquely downward, and the discharge pipe is located directly above the receiving trough. The feed port of the hollow tube is connected to the receiving bin, and the feed port of the receiving bin is located directly below the discharge pipe.

[0008] The hollow cylinder is made of heat-conducting material, and the driving motor and the electric valve are both electrically connected to a PLC controller.

[0010] As a preferred implementation manner in this embodiment, the second telescopic tube has the same specifications as the first telescopic tube.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] The utility model has a reasonable structure and is provided with an air pressure self-balancing adjustment unit, which can automatically maintain the air pressure balance in the heat dissipation copper tube, which is beneficial to improving the heat dissipation of the bearing. At the same time, the number of small weight blocks added to the material receiving trough can be controlled and changed as needed to control the initial air pressure value inside the heat dissipation copper tube when pushing the column upward, thereby changing the heat dissipation effect of the low-boiling point liquid on the bearing. The adjustment is convenient and quick, and the use of small weight blocks with a relatively small volume can improve the weight addition adjustment accuracy.

[0013] In the present invention, the cooperation between the first telescopic tube and the second telescopic tube forms a seal between the material receiving trough, the material receiving bin and the inner cavity of the hollow tube, so that the small weight-adding blocks are placed in the sealed space, thereby preventing dust and other impurities from adhering to the small weight-adding blocks and also preventing moisture from contacting the small weight-adding blocks and causing corrosion and rusting thereof.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Reference Figure 1The shown figure is a new type of pharmaceutical stirrer, with a stirring motor 1 installed on a frame 3, the output shaft of the stirring motor 1 being connected to the stirring shaft 6 through a mounting shaft 2, the mounting shaft 2 passing through the frame 3, the outer sleeve of the mounting shaft 2 being provided with a bearing 4, and the bearing 4 being installed together with the frame 3 through an upper bearing seat 5, the inner cavity of the upper bearing seat 5 being provided with a liquid storage chamber 7, the liquid storage chamber 7 storing a low-boiling-point liquid, the upper bearing seat 5 being provided with a heat dissipation copper tube 8 which is in communication with the inner cavity of the liquid storage chamber 7 and extends spirally upward, and also including an air pressure self-balancing adjustment unit for ensuring the air pressure balance in the heat dissipation copper tube 8, so as to achieve good heat dissipation of the bearing 4 by the low-boiling-point liquid.

[0021] As a preferred implementation in this embodiment, Figure 1 and Figure 2 As shown, the air pressure self-balancing regulating unit includes a hollow cylinder 10 fixedly arranged on the outer wall of the frame 3 through a mounting plate 9 and a column 11 slidingly passing through a limit plate 24. The limit plate 24 is fixedly mounted on the frame 3. The lower end of the column 11 is slidably arranged in the inner cavity of the hollow cylinder 10. The lower end of the column 11 is fixedly sleeved with an elastic sealing ring 21 that slides against the hollow cylinder 10. The upper end of the column 11 is provided with a material receiving trough 12, and the bottom surface of the inner cavity of the material receiving trough 12 is provided with an inclined surface 22. The inner cavity of the material receiving trough 12 is provided with a small weight block, and the lower end of the material receiving trough 12 is provided with a discharge pipe 19 with an electric valve 20.

[0022] A hollow tube 13 with a sealed upper end is mounted on the mounting plate 9, and a spiral push rod 17 driven by a drive motor 15 is rotatably provided in the inner cavity of the hollow tube 13. A discharge pipe 14 is obliquely downwardly provided on the hollow tube 13, and the discharge pipe 14 is located directly above the receiving trough 12. The feed port of the hollow tube 13 is connected to the receiving bin 16, and the feed port of the receiving bin 16 is located directly below the discharge pipe 19;

[0023] The hollow cylinder 10 is made of heat-conducting material, and the driving motor 15 and the electric valve 20 are both electrically connected to the PLC controller.

[0024] Since the heat dissipation copper tube 8 is connected to the inner cavity of the hollow cylinder 10, when the air pressure inside the heat dissipation copper tube 8 increases to a certain value, its air pressure will cause the column 11 to move upward. When more gas is added to the heat dissipation copper tube 8, its column 11 will rise a certain distance accordingly to keep the air pressure in the inner cavity of the heat dissipation copper tube 8 stable, which is beneficial to the timely heat dissipation of the bearing 4. Moreover, since the hollow cylinder 10 is made of heat-conducting material, the heat dissipation area of the gas is continuously increased while the column 11 is raised, which can accelerate the heat dissipation of the internal gas, and is beneficial to the rapid reduction of the internal air pressure, thereby further improving the heat dissipation effect of the bearing 4. At the same time, the number of small and medium-sized weight blocks added to the material receiving trough 12 can be controlled and changed as needed to change the initial air pressure value inside the heat dissipation copper tube 8 when pushing the column 11 to move upward, thereby changing the heat dissipation effect of the low-boiling-point liquid on the bearing 4.

[0025] During use, the electric valve 20 can be operated to make the small weight-increasing blocks in the receiving trough 12 slide downward along the inclined surface due to their own gravity and finally enter the receiving bin 16, thereby changing the gravity applied to the column 11. At the same time, the spiral push rod 17 can be driven to rotate by the driving control motor 15 to transport the small weight-increasing blocks to the receiving trough 12 to increase the weight acting on the column 11, so that the weight adjustment of the entire column 11 is convenient and quick, and the use of small weight-increasing blocks with smaller volume can improve the accuracy of weight addition adjustment.

[0026] It should be noted that, first, the hollow cylinder 10 is made of copper material, and second, a pressure gauge can be set on the heat dissipation copper tube 8, the pressure gauge is electrically connected to the PLC controller, and the internal air pressure of the heat dissipation copper tube 8 is adjusted according to the value of the pressure gauge.

[0027] As a preferred implementation in this embodiment, Figure 2 As shown, the small weight-increasing block is made of metal material, the discharge end of the discharge pipe 14 is connected to the feed end of the receiving trough 12 through the second telescopic tube 23, and the discharge end of the discharge pipe 19 is connected to the feed end of the receiving bin 16 through the first telescopic tube 18.

[0028] Due to the high density of metal materials, small weight-adding blocks made of metal materials (iron or stainless steel) can greatly reduce the occupied volume. At the same time, small weight-adding blocks made of metal materials have a long service life. Through the cooperation of the first telescopic tube 18 and the second telescopic tube 23, the material receiving trough 12, the material receiving bin 16 and the inner cavity of the hollow tube 13 are sealed, so that the small weight-adding blocks are in a sealed space, preventing dust and other impurities from adhering to the small weight-adding blocks, and also preventing moisture from contacting the small weight-adding blocks to cause corrosion and rust.

[0029] As a preferred implementation in this embodiment, Figure 2 As shown, the second telescopic tube 23 has the same specifications as the first telescopic tube 18 .

[0030] The purpose is to ensure that the size of the sealed cavity enclosed by the receiving trough 12, the receiving bin 16, and the hollow tube 13 remains stable when the column 11 moves upward or downward, thereby preventing changes in the internal air pressure during the movement of the column 11 from affecting the movement of the column 11. For example, when the column 11 moves upward, if the air pressure inside the sealed cavity increases, it will resist the upward movement of the column 11; if the air pressure inside the sealed cavity decreases, it will promote the upward movement of the column 11.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
